We currently have 3 sites with about 15 GXP-2000s at 2, and 3 at the third. The 2 larger sites are running 1.0.1.9, the third site is running 1.0.1.12. On straight SIP-SIP calls or outbound calls via an IAX->PSTN gateway, there is no discernable echo at all. Ever. One of the larger sites is connected with 2 BRIs for incoming calls via zaphfc. Generally, there is echo for the first 2 or 3 seconds of a call, then it dies out completely. There are exceptions - I've had reports of echo lasting for the duration of a phone call, but this has usually been down to a callcentre at the other end of the line (probably using an autodialler) where the first few seconds of an inbound call is silence. I guess this must be upsetting the echo training in Zaptel. The other larger site is connected using a TDM400 with 3 POTS lines. There is nearly always echo on incoming calls on these lines for about 30 seconds, after which they appear to be fine. In conclusion - I'm not sure if the GXP2000s are the problem in your scenario.
